--- Comment #12 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:c839965c2ef689cfd62c4ddeb61d872c0d04366c commit r14-11506-gc839965c2ef689cfd62c4ddeb61d872c0d04366c Author: Richard Biener <rguent...@suse.de> Date: Wed Mar 5 14:24:50 2025 +0100 debug/101533 - ICE with variant typedef DIE generation There's a sanity check in gen_type_die_with_usage that trips unnecessarily for a case where the relevant DIE has already been generated successfully in other ways. The following keys the existing TREE_ASM_WRITTEN check on the correct object, honoring this and does nothing instead of ICEing for the testcase at hand. PR debug/101533 * dwarf2out.cc (gen_type_die_with_usage): When we have output the typedef already do nothing for a typedef variant. Do not set TREE_ASM_WRITTEN on the type. * g++.dg/debug/pr101533.C: New testcase. (cherry picked from commit 99a3f013c3bb8bc022ca488b40aa18fd97b5224d)
